execute javascript from textarea

Question

I\'m not entirely sure if this is possible, but I\'m trying to create a mini faux editor in a browser that runs javascript on the page. Here\'s what I\'ve been trying to do

Thnx @Prodigy && @JayC !!!

such a simple solution, I did not know such a function existed :)

using the eval() function did the trick!!!

HTML

 run 

javascript

var cnsl = document.getElementById('cnsl');

function run() {    
    return eval(cnsl.value); // << did the trick ;)
}

//canvas
var ctx;

function setup() {
    var canvas = document.getElementById('canvas');
        ctx = canvas.getContext('2d');
}
setup();​
